Manila file jackets are designed for storing charts, photos & bulky documents that do not fit traditional file folders. File jackets are closed on three sides for document security. Full-height sides keep materials from slipping out, making this a great file for taking documents out of the office. Single-ply, 1/2" high straight-cut tabs are perfect for frequently used files. File jackets are made from 11 point stock & are equipped with rounded top corners on back panel & thumb-cut in front panel.
